formülü

Formülü is the Turkish possessive form of the noun formül, meaning "its formula" or "the formula of it." The base word formül denotes a formula, a concise rule or expression used to calculate, explain, or produce a result. The term derives from French formule and Latin formula, and in Turkish it is used across mathematics, science, and everyday language to refer to a specific rule or prescribed method.

In usage, formül describes the symbolic or literal expressions that represent calculations, recipes, or procedures. The plural formüller refers to multiple formulas. The adjective formüllü, meaning "having a formula" or "formula-based," is also attested and used in technical contexts to describe objects or processes that rely on a particular formula or set of formulas. The possessive form formülü is commonly used to indicate ownership or association, as in "formülü şu şekildedir" meaning "its formula is as follows."

Examples illustrate its range: in mathematics, "Suyun formülü H2O'dur" expresses a chemical formula; in physics or engineering, "Bu formül enerji hesaplamaları için kullanılır" notes a formula used for energy calculations. In Turkish, the phrase formülü often appears after a previously mentioned noun to specify that noun's formula, while formüllü and formüller broaden the concept to formula-based descriptions or collections of formulas.
